Preparation method of nitrogen-doped bismuthyl carbonate catalyst

Abstract

The invention discloses a preparation method of a nitrogen-doped bismuthyl carbonate catalyst. The preparation method comprises the following steps: dissolving 5 g of bismuth nitrate into 100 to 500 mL of dilute nitric acid with mass percentage concentration of 10 to 30 percent, adding 80 to 160 mL of glycine with the concentration of 20 to 180 g / L dropwise under stirring, continuously stirring for 10 to 20 minutes after dropwise adding, generating a large amount of precipitate, separating the precipitate, adding the precipitate into ammonia water with the mass percentage concentration of 10 to 20 percent to prepare turbid liquid, transferring the turbid liquid into a hydrothermal reaction kettle of a polytetrafluoroethylene substrate, putting into a drying oven, reacting at 160 to 180 DEGC for 18 to 24 hours, naturally cooling, centrifuging to obtain a solid substance, washing with deionized water and drying to obtain the nitrogen-doped bismuthyl carbonate catalyst. The nitrogen-doped bismuthyl carbonate catalyst obtained through amino acid combination and the hydrothermal reaction of the ammonia water has high dispersibility and a good catalytic effect.
